BOLSTER FOR RAILWAY-GARS.

SPECHELCA'TIGN forming part of Letters Patent-No. 69 0,073, dated December 31, 1901.

Application tiled November 1,1901. Serial No. 80,814. (No model.)

To all whom t may concern.'

Be it known that I, JOHN F. OOONNOR, a citizen of the United States, and a resident ot' the city of Easton, in the county of Northampton and State of Pennsylvania, have invented a certain new and useful Bolster for Railway-Cars, of which the following is a specification.

This invention relates to improvements in 1o bolsters for railway-cars.

The object of my invention is to provide a new and improved railway-car bolster which is simple in construction, strong, and durable and which can readily be increased or decreased in size and consequent carrying capacity according to requirements.

In the accompanying drawings, in which like letters of reference indicate like parts in all the views, Figure l is a plan view of oneeo half of my improved body-bolster. Fig. 2 is a side view of one-hall' each of my improved body and truck bolster. Fig. 3 is a vertical transverse sectional view of the same. Fig. A is an end View. Fig. 5 is a plan view of a 5 cent-ral section. Fig. 6 is an enlarged detail sectional View of the lower part of one section.

My improved bolster, either a body-bolster or truck-bolster, is composed of a series of 3o sections having the shape of an I-beam in cross-section and placed with the Webs vertical and parallel, the height of the bolster gradually decreasing from the center to the ends. The sections A are made of cast metal with top iianges B to both sides and bottom flanges O to both sides. One edge of each top and bottom flange B and C is provided with a longitudinal groove a, and the opposite edge of each top and bottom flange B and Ov 4o is provided with a longitudinal tongue b, shaped to fit exactly in a groove a in the liange of an adjacent section. Each section A is provided on its vertical or web portion with lateral tubular projections D, which are a5 of such length that when the tongues b of one section A are within the grooves of the adjacent section the ends of such tubular projections on two adjacent -sections will abut. Headed bolts F or long rivets are then passed 5o through the several tubular projections, and

heads are formed on the projecting ends of the same, so as to hold the several sections A, forming a bolster, securely together.

Each bolster may be built up of a greater or less number of sections, and the flanges of the sections may have greater or less width, as shown in Fig. 6, and likewise the webs may be cast heavier or lighter and with larger or smaller or with a greater or less number of openings J.

As shown in Figs. 1 and 3, the bolsters are composed each of four sections A, and the inner or central sections each have a semitubular sleeve II for the king-bolt. The halfround sleeve must always be provided when the bolsters are built up of an even number of sectionsA; but when an odd number of sections are used the central section must be provided withatubularsleeve Hfor theking-bolt, as shown in the drawings. The sections A are provided with openings J in the web or upa right portions, and along the edges of these openings flanges K are formed, which project laterally from the web just as far as the top and bottom anges and on one sideof each section have a tongue on the free edge and on the other side have a groove like the top and bottom flanges, so that when the sections are assembled and united the tongues on the flanges K of one section pass into the grooves in the lianges K of an adjacent section. The center bearing L, the side bearings M, and the guides N are secured to the bolsters.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A railway-car bolster composed of a series ot flanged sections placed vertically side by side, the flanges of the adjacent sections being engaged substantially as herein shown 9c and described.

2. A railway-car bolster composed of a series ot flanged sections, placed vertically side by side and united, the flanges having tongues and grooves which engage with those of adjacent sections, substantially as herein shown and described.

3. A railway-car bolster composed of a se ries of flanged sections placed vertically side by side and having tubular projections on the 1 oo sides which project as faras the langes, substantially as herein shown and described.

4. A railWay car bolster, composed of Banged sections, placed vertically side by side and having openings in the Webs and flanges along the edges of said openings, substantially as herein shown and described.

5. A railway car bolster composed of flanged sections, placed vertically side by side and provided with openings in the Webs and flanges along the edges of said openings, all the ianges having longitudinal tongues or grooves in the outer-edges, the tongues on one section fitting in the grooves of an adjacent section, substantially as herein shown and described.

6. In a railway-car bolster, the combination of a series of flanged sections placed vertically side by side and having tubular prol jections on their webs, which tubular projections eXtend as far as the flanges and bolts passed through said tubular projections, substantially as herein shown and described.

Signed at Easton, in the county of Northainpton and State of Pennsylvania, this 24th day of October, A. D. 1901.
